To all whom t may concern.'

Be it known that I, -HAAKoN l?. HANsoN,

`stan'chions, and its object is to provide a stanchion of particularly flexible, strong and -cheap construction.

In accordance with the invention the stanchion `structure is made in most `part of tubing and structural steel and ywith ia minimum amount of special castings, thereby cheapening the structure and the castings are of such nature that the stanchion when closed gives great freedom to the head of the animal while any of the stanchions may be unlocked, when desired, individually, or two or more stanchions, up to the full number, may be locked or unlocked 'simultaneously. l The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the .showing of the drawings, but may be changed and modied so long as such changes .and modi-tications mark no material departure from the salient features of the invention as expressed in the appended claims.

Referring to they drawings, there is'shmyn .in Eis .1. a Series'. of; A.,

- to any material extent.

ing a stall arch or head 1 erected on a suity able flooring and preferably formed of pipn lng bent into shape, each arch or head including, in the preferable form, a single piece of piping.

Extending along the top of the stalls and supported on the crown portions of the arches 1 is a master bar 2 carried by guide blocks 3 fast to the top of the crown of each stall arch. Secured to the crown or top of .each stall arch in spaced relation below the latter and close to it is a bar guide 4 preferably though not necessarily of channel form, such channel bar being readily obtainable upon the market and possessing the requisite strength and cross sectional shape for the purposes of the invention. The bar 4 has a length considerably less than the width of the stall arches or heads. Mounted .on the bar 4 to slide thereon are two castings or movable blocks 5 and 6 respectively. The casting 5 has a head portion traversed by the bar 4 so that the-casting will move lengthwise of the bar 4 without turning or rocking At one end the head of the casting 5 has a depending lug or journal 7 lof rounded cross section to constitute a swivel and at the lower extremity carries a washer S heldv to the swivel end of the casting by riveting or heading over as indicated at 9. Similarly the casting 6 has a passage through which the bar 4 extends so that the casting will lie snugly upon yet slide freely along the bar. Depending from the head of the casting 6 is an angle arm 10 having a laterally extended extremity 11 at the end of which latterV there is a depend-ing lug or journal 12 constituting a pivot or swivel, which, like the swivel 7, carries a washer 13 held in place by riveting or heading over the end of the swivel 12 as 'indicated at 14. The lugs or journals 7, 12

cfg-theV bracket 6y will underride thefswivel 15 swivel head 21 permitting the stanchion'to 7 of the bracket 5 and the angle arm 1Q is so related to the bracket 15 thatthe swivel 12 may be brought close enough Vto the bracket 15 to underride the swivel-7 in alinement therewith on an upright axis. Atthis time the two castings 5 and 6 are in Vabutment midway of the length of the bar Vt. Each bracket andf16 is fast to the vupper end of Varespective stanchion member 17 and 18, these stancliion members being .connected at theirs-lower ends by apivot pin or v bolt 19 andthe lower pivoted end oi' the stanchion is connected by al chain 20 tothe lower ends'of the upright portions of the stall arch, the connection being by way oi a turn inV its connection withthe chain. Each 'bracket 15 and 16 terminates Yin a 'foot'22 connected by bolts 23, 24C to the upper ends l 3ro .of the stancliion members 17 and 18, which stanchion members are formed of channelv steel and have their upper ends bent at an angle toward each other Vto form a stanchion of customary shape. The arrangement is such that when the castings 5L and 6 are moved lengthwise Yof the bar 4t and this movement is toward each other, the 'members 17 and 18 of the stancliion are brought close enough together to properly embrace the neck of an animal and when separatedthe animalmay withdraw its headv i"rom.the stanchion, yas is customary' where certain Y. types of stanchions are provided. VThe loose Y swivel connectionlat the bottom of the stanchion and theV other swivel connections atl the top of the s'tanchion, when the stanchion is closed, permit great freedom oic movement 'of the head of an animal confined 1n the fstanchion, about an upright aXis, such freedom including 907 or more in opposite directions without any liability of the animal loosening its head ironithe stancliion.

lSecured inany suitable manner to vthe Y arch lof the stall at or near one end of the Vbar 4 is a post or Support 25 rising toward the top of the arch, and pivoted intermediate of its length to the upper end or the post isa lever 26 rockable inthe direction of the lengthV of the archand master bar' 2. The lever'26 .at oneend is formed into'Y or provided with a handle`27 and at the otlierend lis connectedV by a link 28 to the-casting 6.

Adjacentto the handle 27 the lever has pivoted thereto one end of a link 29, the other vend of which is extended and pivoted to the casting 5, the two castings '5 and 6 constitut "ing slidable stanchion holders. At that end of the lever 26connected to the link 28 `there is V.provided Yan oiiset'lug 30 and at the end -of thelever adjacent to the handle 27 there is an offset ear 31, the latter carrying a pin y32 adapte'dfto be engaged in a notch 33 Ain one end Vof aV pivoted'link 3 4 connected by a pivot'35 to the master bar 2.

The lfe'vei726 providesl a manipulating VVshown in Figs. 1 and 2.

3() atthe end o'l' the link 26 remote from the means whereby the slidable stanchion holdersorblocks 5 and 6may be spread apart as shown in Fig. 3, or brought together as lVhen the lever 26 is in the position shown i in Figs. 1 and 2, those ends of the links 28 "and 29 connected to the castings orstanchioii v'holders are close to each other and tl e lever 26 and link 29 are about in alinement one to. the'other with that end of the link 28 75 pivoted to the lever 26V past-center with respect to the endof the link 28 pivoted to thestanchion holder 6. v,Moi'eovei", the *link 29 isin engagement with the stop or lug handle 27. This-constitutes a lock of the over or past-'center type, preventing acci-VY dentalloosening of the stanchionswhen Vonce they are locked together. lAt the same time f an intentional movement ofthe lever 26 toward the center of the stall will immediately unlock the stanchion Vmembers and separate them to thefullextenuas shown in Fig. 3,

thereby permitting the withdrawaloi:l the Vheadofthe Vanimal ifpreviously confined in th'e stanchion. .Eachf stanchion may be 'operated independently of the others if so desired, `but' if it be preferred to operate two or morestanchions at the same time the Y link 34 isi utilizedfby moving the notched end33 so as-to engage over the pin 32,-thus connecting the master bar 2 to the lever or ,levers 26, Now whenafnyv one of the levers is operated all theV other levers connectedKY to the master bar by the links 34 will partici,- 100 depending angle arm longer Vthan Y said luv.y

and a second bracketswiveled upon the 'end of saidangle arm and secured to thefother 11,5

3. In stanchion structure, a stall arch, a rigid guide har having a length less than Y the Width of said arch and secured thereto in spaced relation below the top of said arch, blocks embracing said bar and slidable thereon, one of said blocks having a depending angle arm, stanehion members mounted to swing to and from each other at their upper ends, and means for swivelly connecting the upper `ends of said members to one of said blocks and to the angle arm of the other block, whereby when said members are closed the swivel connections will lie in the same vertical line but different horizontal planes, links individually connected to said blocks, and an operating lever connected to said links.

In testimony that I claim the foregoing as my oWn7 I have hereto aiiixed my s1gnature.
